Notes:
• For some paper sizes like letter, legal, and A4, squeeze and slide the length guide tab backward to accommodate their
length.
• When loading legal‑size paper, the length guide extends beyond the base leaving the paper exposed to dust. To
protect the paper from dust, you can purchase a dust cover separately. For more information, contact customer
support.
• If you are loading A6-size paper in the standard tray, then squeeze and then slide the length guide tab toward the
center of the tray to the A6‑size position.
• Make sure the width and length guides are aligned with the paper size indicators on the bottom of the tray.

letterhead faceup with the bottom edge of the sheet toward the front of the tray.
